Similar numerals designate like parts in the The head 5 ofl casing 2 1s formed or proseveral ligures. vided with a central longitudinal opening The invention is shown applied to the cenforming seat 6 for the reception of atwo-part tering mechanism of Patent No. 749,149, of bearing, of which one section is adjustable 9o which l is the prime mover, having a fixed with respect to the other and both together range of motion, 2 the casing for the springwith respect to the head. To these ends the main section 7, preferably cylindrical, is titted to reciprocate longitudinally in the recess in head 2, being held from rotation therein by suitable means, such as a pin 10, engaging a groove 11, and it is provided with a transverse opening 1Q for the passage of the head of prime mover or lever 1.

At one side of opening 12 is formed a bearing-surface 13, adapted to receive the spherical head of the lever. The opposing bearing or section 14 is threaded into one end of the main section 7 and is provided with a threaded extension or stem 15, projecting beyond the end or' head Q.

Threaded into opening 6 and surrounding stem 15 is a nut 16, and against the outer face ot head 2 is litted a washer forming the seat for a key 17, the latter flanged to engage said washer and provided with a barrel engaging said nut 16 in a manner to permit independent longitudinal motion, but compel simultaneous rotary movement, as by flattening the sides of said key and litting major diameter into correspondingly-shaped seats in the nut. The stem 15 carries a nut 18, seating upon the end of key 17 and serving to clamp and hold the bearing in adjusted position.

To adjust the two sections of the bearing upon the lever or prime mover, nut 18 is loosened and the key 17 turned in a direction to withdraw nut 16, thus releasing the bearing as a whole, whereupon by turning stem 15 the section of the bearing attached thereto may be advanced or retracted, as desired, to release the prime mover, to apply the bearing thereto, or to reset the two sections for taking up lost motion due to wear. This does not involve any interference with the members ot' the two centering systems, and to establish, reestablish, or secure the proper positioning' of said members relative to the prime mover the key 17 is turned to advance or retract the nut 16, against which the bear-- ing abuts, after which nut 18 is tightened up, the latter operating' in a twofold capacityas a brake to resist accidental displacement of the adjusting devices for bearing 14C and as a clamp Jfor holding the main section 7 lirmly clamped against its adjusting nut or member 16.

Having thus described our said invention, what we claim as new, and desire to secure by Letters Patent, is-

1. In a centering mechanism for type-casting machines, such as described, the combination with the spring-box casing Afor the duplex actuators and the prime mover therefor, of a bearing adjustable in the line of movement of the prime mover and provided with relatively adjustable members between which said prime mover is received.

2. In a centering mechanism for type-casting machines such as described a spring-box for duplex actuators provided with a separable bearing and means for adjusting the latter bodily in a direction parallel with the path or' the prime mover engaging said bearing.

3. lIn a centering mechanism for type-casting machines such as described, a spring-box for duplex actuators provided with an adjustable bearing for the prime mover the same comprising a main section supported in ways on the casing and provided with a bearingsurface, an opposing bearing-surface movabl y mounted upon said main section, and means for adjusting said main section and the bearing upon the casing.

11. In a centering mechanism for type-casting machines such as described, a coupling for connecting' the spring-box casing with the prime mover consisting essentially of a main bearing block or section supported to reciprocate in a recess in the head of the casing; an opposing bearing block or section threaded into the main section; a nut threaded into said recess, for positioning` the bearing-'blocks therein, and means for clamping said bearingblocks against said nut.

5. In a centering mechanism for ty pe-casting machines a coupling for uniting the springcasing and its lever or prime mover, the same comprising a main bearing-block movably supported in a recess in the head of the casing; an opposing bearing threaded into the main bearing and provided with a threaded stem; a nut threaded into the recess at one end of the main bearing-block and engaging the latter; a key surrounding said threaded stem and engaging the adjusting-nut; a washer engaging said key; and a nut engaging said threaded stem and the key.
